INTRODUCTION 3 STORMWATER MANAGEMENT PLAN OVERVIEW The City of Hendersonville is a federally designated National Pollutant Discharge Elimination System (NPDES) Phase II community and operates under the authority of the Stormwater Management Program which operates as a division of the Engineering Department. The North Carolina Division of Water Quality renewed NPDES Phase II Permit NCS000489 to the City of Hendersonville November 30, 2016 – November 10, 2022. The Stormwater Management Plan is the City of Hendersonville’s program to comply with NDPES Permit NCS000489 authorization to discharge Stormwater from the Municipal Separate Storm Sewer System (MS4s) located within the City of Hendersonville Jurisdictional Area. The plan is a guidance document used by City staff and the general public. STATUS OF IMPLEMENTATION The City of Hendersonville is pleased to report progress for year 12 compliance with requirements of NPDES Phase II permit in the following six minimum control measures in the plan: x Public Education and Outreach x Public Participation and Involvement x Illicit Discharge Detection and Elimination x Construction Site Runoff Control x Post-Construction Site Runoff Control x Pollution Prevention and Good Housekeeping for Municipal Operations On April 7, 2011 the City of Hendersonville Council approved Stormwater Ordinance No. 11-0419 Article III WATER QUALITY The City of Hendersonville is delegated by the state to enforce the Stormwater and Illicit Discharge regulations within our jurisdictional area. The city has adopted and enforces a stormwater ordinance. (Chapter 24 Article III of the Code of Ordinances) The city reviews and approves all development plans associated with grading, stormwater, and erosion control. For projects that cumulatively disturb more than one acre a formal plan is required. All formal plans are required to be prepared by a qualified registered NC professional engineer or landscape architect. For projects that disturb less than an acre and are not part of a larger development are exempt from the stormwater ordinance. For all other projects, stormwater controls must be designed by a licensed professional and installed. The city requires 85% removal of Total Suspended Solids and also requires that the post construction discharge not exceed pre-development discharge for the 2-year and 10-year storm event with the ability to pass the 25-year event.
